OF PATERSGN, NEW) JERSEY, A COR- UPPER-SHAPING MACHINE.

Application filed May 31,

whom it may concern: mown that l, lrirrnjon Barns, a sul jet oi the King of England residing at Leicester. Leicestershire, England, have inrented ertain improvements in Upper- Shaping Machines, of which the following lescriptiom in connection with the accompanying drawings is a specification, like reference characters on the drawings indicating like parts in the several figures.

'ihis invention relates to upper shaping machines, and has for an objectto provide an improved. organization of means for conforming upper materials to the contour of a last or other shoe term. The invention is herein illustrated in its application to the shaping of the uppers, of veldtschoen or stitchdown shoes but it will be recognized that in various novel aspects the invention is not limited to the manufacture of shoes oi? that parti ular types A feature of the invention consists in a novel organization comprising a flexible member herein conveniently termed a wiper, for drawing or wiping an upper to the contour of a form about the end of the form, together with means for controlling the marginal portion of the upper in such manner as to maintain the upper in an unwrinlrled condition about. the end or the form and to render the flexible wiper ell'ective to draw the upper tightly and smoothly to the contour of the liOlnL The construction shown comprises means for clamping the margin oi the upper out spread about the toe end ol? the form from one side or the toe to the other with yielding pressure permitting the upper to slip at any point or points where the tension pro duied by the indrawing pull of the wiper tends to become excessive, thus assisting in equalizing the tension and in maintaining the pressure of the wiper uniform on the dither-out portions of the upper which it engages. (in stitchdown shoe work, the clamping means illustratedis adapted to shape or mold the margin of the upper to DIORlHL'Q an out-turned flange characteristic o'l that kind of work. The machine herein shown is constructed also to pull or stretch the upper over tie form by "relative movement between the form and the marginal clan'iping means, and a hirther feature of Specification of Letters Patent. Patgnted Ju 13 1922 1916. Serial No. 160,950.

theinvention is to be recognized in an organization such as hereinabove set forth including means for pulling the upper over the form.

A tin-ther teature or" the invention consists in a novel organization of upper pullmg means. lin this part oli the invention important objects in view are substantially to equalize the tension of the upper over different portions of the contour of the Form and to loredraw the upper while establishing the correct lines required for the finished-shoe. The desired results are effected in the construction shown by means which clamps the marginal portion of the upper yieldingly about the end of the form under such pressure as to permit the margin to slip at points of excessive tension, together with. opposite side grippers which engage the upper farther rearwardly at the sides of the form, and operating means for effecting relative movement between the form and the clamping means and the grippers to pull the upper both heightwise and lengthwise ot' the form at the toe end and at theopposite sides. In this manner the, strains on the diflerent portions of the upper are substantially equalized and the entire forepart of the upper is subjected also to a toredrawing tension without relative displacement of parts atthe end and the sides such as might distort the line of the tip seam where the shoe is provided with a tip. tluch means for pulling the upper over the :l orm, when combined with means for drawing or wiping the upper into conirixrmit tothe contour of the form as hereinabove set forth. produces an upper completely shaped over the forepart of the form without substantial differences in the strains applied at diiierent portions of the upper such as might lead to loss of shape in the vear ot the shoe, and without wrinkles in those parts of the upper which have been Found heretofore particularly diliicult to shape in a smooth and satisfactory manner.

The above and other features of the invention, including also a novel construction of upperclamping means and various other details of construction and combinations or parts will now be described with reference to the accompanying drawings and pointed out in the claim.

Fig. 1 of the drawings is a side elevation partly in section showing an illustrative machine in work receiving position.

Fig. 2 is a view to contrast with Fig. 1, Fig. 2 showing the machine at a certain stage in its operation upon a shoe.

Fig. 3 is a detail view in part sectional side elevation of certain alter-native mechanisms for the machine.

Fig. i is a right-hand elevation of parts shown in Fig. 1.

Fig; 5 is a right-hand elevation of parts shown in Fig.2.

T 20 machine shown comprise a shoe form or last support, herein frequently termed a tread rest, and operating mechanism thercfor: a toe clam or retarder and side riw pers. and operating mechanisms therefor by which moo-operation with the last support, the upper is stretched and adjusted; and a mechanism for manipulating the stretched upper into lasted position about the forepart of the last. These mechanisms-will be described in the order enumerated and then their joint operation explained.

The last support 1 has a tread resting face provided with projections torestrain movement of the tread i'ace ofthe last, or of an innersole over the same, and said support is mounted to swing upwardly about a fixed pivotfi located a substantial distance below the shoe and as showiu under the rear part of the shoe.

The swinging ot' the last support is effected by connection with the power operating mechanism of the machine. The support is engaged under the ball of the last by a plun gcrt pivoted to the left-hand end of a lever 5 which has a fixed fulcrum atG and the forked right-haml arm of which is connected by links 8 and a cross-head"9. Figs. 4 and 5, with a rod 1.0 which carries an abutment 12 that is adjustable on the rod to provide more or less lost motion between the rod and the last support operating cross head. This provision is desirable because the rod is also connected, as will be doscribedfwith the side grippers and the re tarder which should be operated to seize the upper before the support is moved to raise the last.

The last support operating rod has a threaded adjustment in a cross-head 15 which is connected by links 16 with a link 18. Figs. 1 and 2 that has a strap encircling an eccentric 20 on the power shaft 21. The described organization such that rotation of the eccentric draws down rod 10 and. after the lost motion between abutment l2 and cross-head 9 has been exhausted. rocks lever to move the tread rest and the last upwardly and l'iackwardly about pivot 2.

The clamp or retarder comprises two flat plates 30, 31 which are recessed in their edges toward the last support substantially in V-shape to. receive the forepart ot the last. The plates are adapted to clamp between themselvesthe margin of the upper continuously from one side of the toe around the end of the toe to the other side of the toe and trictionally hold the upper so that on a predetermined tension being exceeded at any point or points the upper may slip between the plates to permit relative movement. of different parts of the upper in ac cordance with requirements of ditl erent parts of the toe portion of the last over which the upper is being shaped.

The lower retarder plate is rigidly mounted on a table coi'nprising the top at a frame member 32, in which the love 5 is pivoted. The upper plate 31 is carried loosely on a plunger 35 between a shoulder of which and a collar 36 the plate is confined. The plate is overlaid by a rap 38 the top face of which is convex and tits the concave lower face of the collar so that the retarder plate can tip to adjust itself to the work. A spring 39 encircles the plunger andv is confined between the shoulder thereon and a shoulder on the cap plate to maintain the curved faces in contact and a pin 3? rising from the frame member 32 assists in holding the plates 30,31 in suitable relation and limits tipping of plate 31.

The upper retarder plate is moved down to clamp the margin of an upper introduced between the plates by a lever 40 connects-l to the plunger 35 and fulcrumed at its righthand end to a post 42. The rod 10 extends loosely through the lever 40 and is encircled above the lever by a spring 4-5 through which upper clamping pressure is applied. the ten slon of the spring being regulated by a nut 44: on the upper end of the rod. A second and weaker spring 46 is confined between the lever and; the frame, and the rod has collars 47, 48 which, in the movement of the rod up and down act respectively to relieve the lever of the pressure of the spring or 4:6.

It will now be understood that movement is transmitted from the power shaft 21 through rod 10 and spring to and connections to operate the retarder to clamp the margin of the upper and that this occurs while the lost motion is being used in the connection of the rod 10 tor raising the la t support.

The side grippers, Fig. 6. are located to engage the upper at each side of the last in .a position appropriate for the application of transverse draft or strain to the upper to which longitudinal draft is applied by relative movement of thelast and the retardcr. These grippers each comprise an inner jaw formed on a tubular bar 50 that is movable endwise in a gripper guide and is upheld by a spring 5% confined between the lower bearing :oi the guide and a collar 53 on the ear. The outer aw 55 is pivoted to the inner jaw and connected by a link to an operating rod which is movable in the tuloular bar by linlc connection with a cross-bar 60. The cross-bar is pivoted. on a longitulinal bar (32 so that it constitutes an. equalizer between the two side grippers and it is extended laterally to form. handles by which the operator can adjust the torepart oi" the upper transversely across the last. The longitudinal bar (32 is carried on a vertically movable rod Fig. i, that carries a slidinasleeve resting on a spring (36 encircling the rod and supported at its lower end by a collar 66 test on the rod. A lever 70, 'l'ulcrumed to the frame, is pimted. to the sleeve and is connected to the link 18 to receive motion trom the eccentric 20 and tr mit it through spring 66 to pull down toe si le grippers.

The side gripper ides 52 are pivotally supported on a sli .e '79,, 6.. and are adjustably connected togetherhy a right and left thr-aded rod 73 by which they can be set for widths of shoes. The slide 72 .is mounted on a stationary "frame bar 74.; that extends longitudinall of the machine and the slide movable lengthwise, oil that bar by a screw rod '75 having a knurled head, Fig.5. 1.. to adjustthe side grippers toward and from the retarder for lengths oi"? shoes.

- The side grippers have an automatic movement toward the toeto toredraw the upper by connections which derive their movement from the same eccentric 'tl'ODl which the pulling motion derived and the last rest li ttingmovement earlier described. The screwrod. has two collars fasten it the inner one at which constitutes sliding bearing; tor the rod in the bar Between the collars is a block to which is connected the lower end. ot a lever that is connected by short linl': to the frame and by a longer upper link to a lever 82 that is tulcruined on b r 7 51-. The lower. arm ot the lever .82 is connectedby av link to the rigi ht-liand end (it the vertically movableno: 62 and when the bar is moved downwardly the link and lever arni operate as a dc to swing the lower end of lever 80 iard the right and more the side grippers 'i o i w ard l y.

The stretched upper is manipulated into laste-.l. position around. the toe by drawii'rcit to and Wiping it into conformity with the edge at the last bottom inthe case of stitchdown shoes hr. 21 wire loop 85 or like tleizihle' wiper extending; about the torepart and adapted to accommodate itself to the last cmtour and be tightened hard around the work. The wire loop 85 is shown as attached to the power-operated lever 80, the upper end o'l" which is 'l'orlred above its opcrating); lift: the lioi .part of the last, Fig. 2, above the retarder where it one-rates to draw the up per to-the edge otthe last. I

From the foregoing description .it will be understood that the organization ot the maoh ine is such'that whe and the loop extends around last. with or without an innersole on its tread face, is applied to the support or sole rest 1 with the margin of the upper between the retarder plates 3O. 81. and the jaws oi? the side g1lp} )61S. llli lasting loop 85 being in place shore the retarde-r. and power is applied the several. mechanisms will be operated tollows:-- The retarder plates will yieldingly clamp the mi. in oi the uppe around the toe and hold it outspread. the side grip 'iers at about the same time seiz' ig the upper at the sides of the ball. The shoe support will. thenbe rocked about pivot 2 to carry the last upwardly and backwardl g to COHtOin'l the upto the contour of the top lace oi the torepart ot the last by stretching it longitudh nally and transversely ot the shoe between the last-on the one hand and the retarder and side grippers on the other hand. the

retarder giving up stock as required at the points where the greatest. strain is eliected and the liSt bein inoved to a position in which its tread itace is above the. clamped margin. oil. the upper. In the meantime the side grippers inove downwardly and also, through lever 80 and rod 75. are moved forwa'rdly to carr; the margin ot the upper, and the. ends of thetip sea-m it it is acap toe shoe, forwardly to balance the forward displacement of the upperover the top jlfac'e "ot the last by the pull oi? the .retarder.

l Vhile the upper being. stretchedand conformed to the top 'taceoi the. last the lasting loop is pulled rearwardly causing it to adapt itself to the shape of the toe ot the lastnand it draws the upper to and wipes it into contormity with the edgre oi the last bottom to form. in a. stitclrdown shoe, the tucl oor crease l which. the upper its the angle termed by the side oi the last and the projecting margin of the sole.

contemplate. the u a. of a stop clutch of any well-known type which will bring: the machine to rest with the 1 arts in thciposition sluiiwn in l 2 to allow a toe binding wire to be applied. in the crease. termed and held by the lasting loop and to be suitably anchored. as tor example to a tack located in the heel end face of the shoe. machine is restarted the parts a e returned to their initial position and the upper i. "freed from the retarder and ippersto perl I mit the shoe to be withdrawn from the loosened lasting loop and the support 1.

In the modification shown in Fifzjfgthe last support 101'. is extended. rearwardlvto support an adjustable heel rest 102 which,

entirely prevent-s longitudinal rearward l' i hen the incr ment of the last relatively to thelast srugport. The last support is pivoted. at 10 upon. a bracket 10G projecting from the trams of the machine. The last support is held lightly in contact with the plunger 4 by a spring 105 connecting the support and lever 5. Upon the bracket 1.06 is also supported a, shatt 107 carring rolls, one of which is seen at '1 8. over which pass the side portions of the loop 85, each end of the loop being; attached to across head 110 on the cod of a rod 112 guided in a bracket 113 on the frame. The rod passes loosely through an opei'iinp; in a lever 120 which is pivoted on the frame at 121 and is connected to the sleeve (55 by a link 122. Pinned to the rod 112 a collar il-l which is arranged to rest upon the lever 120, and confined on the rod between the lower side of the lever i520 and a nut L15 on the end oil? the rod is a )ring 12-33 which tends to depress the rod relatively to the lever while permitting relative movement between the lever and the rod. i

The operation of the construction shown in Fig. 3 will be readily understood from the preceding description. It will be noted that in this construction the wire loop is operated by the lever 120 through the yielding connection aitorded by the spring 123, and also that the yieldingquality of the pull applied to the loop may be varied inde iicndently of other means by adjustment of the nut 115. Y i

If desired, the upper may be prepared for the operation of the present machine by molding its heel end portion in a special molding operation such, for example, as do scribed in prior United States Letters Pat ent No. 1,156,897, and in such case the shoe is ready, after the operation of this machine, for the shoe bottoming operations, with the aid sometimes of more or less shank lasting. It will be understood that on stitchdown shoe work, as illustrated, the clamping means shapes or molds the margin otthe upper about the toe into an outturned flange "for attachment to the sole or insole.

It will be recognized that the foregoing disclosure includes a novel method for use in the making of shoes, which is not claimed herein since it forms the subjecbmat-ter of a divisional application, Serial No. 423,623 filed on November 12. 1920.
